CHARLES GANDEE, on nEW-YoRK, ASSIGNOR OF ONE-HALF To ALBERT e. STORY, OF LITTLE FALLS, n. Y.

JOURNAL-BEARING FOR CAR-AXLES.

SPECIFICATION forming part of Letters Patent No. 312,436, dated February 17, 1885.

Application filed May 15, 1884. (N mndel.)

To all whom it may concern:

Be it known that I, CHARLES E. CANDEE, of the city, county, and State of New York, have invented a new and Improved Journal- Bearing for Car-Axles, of which the following is a full, clear. and exact description.

The object of my improved construction is to distribute the friction and strain in journalbearings over a large extent of surface, so as to save wear upon thejournals, and also to support the journal against side strains;

The invention, therefore, consists of the hereinafter described and claimed combinations of parts.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of a journal-box with my improvements,'the side cap being removed. Fig. 2 is a vertical cross-section of the same. and Fig. 3 is a cross-section of the box in modified form. Fig. 4 is adetail View. The box A is of circular form, having seats a for the springs, and the cap b at the outside is removable, to give access to the interior. Within the box, and cast with it, is an abutment, 0, which is of an approximate circular form at its outer periphery, between which 0 and the interior surface of the case is a space that receives the ring B. At the top the abutment 0 receives in a recess the boxing d, that surrounds the journal 6 of the axle exceptat the upper part, where the ring B bears on the 5 journal, as shown in Fig. 4c, the boxing being made with ribs d,that take into-recesses in the abutment to prevent rotation. The ring B also bears upon three ro1lers-a large roller,

f, and smaller ones, 9 gthat retain the ring 0 in place against the upward strain of thejournal. The roller f has journals seated in boxes h h at'front and back of box A, and in a line vertically below the axle-journal, while the side rollers, g, are set in mortises in the abutment 0 upon fixed axles i. Upon the end of the journal e is a spur-wheel, 70, that engages a toothed ring, I, attached to ring B, so that the rotation of the axle causes a slow movement of the ring.

It will be seen that the friction-ring B being of large diameter compared with the journal 6, the surface of contact between the two is small, and thatitis continually changing by the rotation of the ring. The abutmentcsupports the journal 6 firmly against side strains and lurches tending to twist the axle, so that the friction-rollers are relieved of such strains.

In the modification shown in Fig. 3 the large rollerf is at the center of box A, and is formed integrally with acap, m, that is made with or 6 attached to ring B, and closes the outer side thereof, except that openings m are made for insertion of spur-wheel k. Asmaller roller,

9, isjournaled in the abutment 0 on the center line. In both forms the rollers are upon 55 journals that turn in boxes instead of turning on axles, as is usually the case, and the axlejonrnal 6 being surrounded bya boxing,d, of hard metal, the wear is taken from the abutment.

I prefer to use the gearing to insure rotation of the ring; but the contact of the journal and ring may be alone depended on for that purpose.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The hearings for journals, consisting of friction-ring B and rollers f g, combined with a box having a central abutment, c, substantially as described.

2. In a journal-box, the spur k, combined with frictioirring B, having the toothed ring Z, and journal 6, substantially as described.

3. The friction-ring B, provided with cap m, and formed integrally with roller f, and 85 also made with openings at, substantially as and for the purpose specified.

CHARLES E. GANDEE.
